How do I troubleshoot and fix OneNote add-ins?

1. Check if the add-in is disabled – enabling the add-in might be all you need to do to fix the issue.
2. Check the settings of the add-in – different settings can sometimes cause conflicts.
3. Try using a different browser for the add-in – in some cases, one browser might work better than another for the add-in.
4. Check if the add-in is up-to-date – if it’s not, try updating it to the latest version to see if that fixes the issue.
5. Try uninstalling and reinstalling the add-in – this often works when nothing else does.
